Tvs Motor Company — Warranty Problem

Address:

Krishna Motor, Paschim Medinipur, 721101

Dear Sir/Madam

I have a TVS Radeon bike. I did all servicing time to time. But 20000 km ago the engine was making a very loud noise.I go toKrishna Motor Service Center before 7-8 months ago. Engine problems were not solved due to lack of parts. They assure me that when parts come engine will be repaired.The problem is not solved even when I go to again servicing. They told me they would only charge for packing and engine oil. My bike is now going 39000+km. Recently 5th Aug again go for servicing. They told me all the parts came and solved the big noise of the engine. They charge me for repairing all parts around 5000+rupees. My question is what is the warranty ?
With Regards
